Step 5: Install Components

Thread the LEDs wires through the top of the candle and connect them to your circuit board. Insert some batteries and ensure it all still works and is connected correctly. Place the circuit board in the cavity and slot the battery pack into its socket to seal it all up. As mentioned earlier, the battery pack should fit firmly. If not, you made need to add a little padding to fill the gaps and get a tight fit. I secured the switch to the side of the battery pack with some hot glue to finish it off.

To make the LED look more at home on the top of a candle, add small dobs of hot glue and shape with a toothpick until you've built an imitation hot glue flame. You're done! Build your own customised candles like the three candle coffee and chocolate version shown in the intro of this instructable.
